Abstract
A device for illuminating a posterior segment of an eye may include multiple channels. Each of the channels may include multiple illumination paths such as a first region illumination path, and a second region illumination path. The first region illumination path and the second region illumination path may be illuminated at different times such that a first region and a second region may be imaged without interference from a non-illuminated illumination path.
Claims23
A device for illuminating a posterior segment of an eye, including:
- a plurality of channels, each of the plurality of channels including:
- a first region illumination path;
- and
- a second region illumination path;
- and
- wherein the first region illumination path and the second region illumination path are illuminated at different times such that a first region and a second region may be imaged without interference from a non-illuminated illumination path, and
- wherein the plurality of channels converge at a single point proximate the eye, the device further comprising a multi-sectioned wall disposed at the single point.
A device for illuminating a posterior segment of an eye, including:
- a plurality of channels, each of the plurality of channels including:
- a first region illumination path;
- and
- a second region illumination path,
- wherein the first region illumination path and the second region illumination path are illuminated at different times such that a first region and a second region may be imaged without interference from a non-illuminated illumination path,
- wherein a first channel of the plurality of channels further includes a base component, the base component comprising:
- a camera within a casing, the camera aligned with a center axis of the first channel;
- a first illumination source associated with the first illumination path and located outside of the casing;
- an aperture associated with the first illumination source;
- an illumination condenser system to provide beam control and steering of light from the first illumination source, the illumination condenser system located outside of the casing and orthogonal to the center axis of the first channel;
- and
- a baffle to block stray illumination from the first illumination source, the baffle approximately even with a top of the casing within which the camera is disposed.
A device for illuminating a posterior segment of an eye, including:
- a plurality of channels, each of the plurality of channels including:
- a first region illumination path;
- and
- a second region illumination path,
- wherein a first channel of the plurality of channels further includes a
- third illumination path, and
- wherein the first region illumination path and the second region illumination path are illuminated at different times such that a first region and a second region may be imaged without interference from a non-illuminated illumination path, wherein the first illumination path illuminates only an outer radial portion of the posterior segment of the eye, the second illumination path illuminates only an inner radial portion of the posterior segment of the eye, and the third illumination path illuminates only a medial portion of the posterior segment of the eye.
